Yeah, I will need a detailed concrete plan to go to our routing guru and manager for approval. I doubt they will allow it to run on production routers, but we have some older gear in our lab I might be able to re-purpose.
On thing I'm not clear on. As a potential admin of a AMPR POP would I have to manually configure GRE tunnels for every local gateway that wants to connect ? That could be headache.
